AMY GOODMAN: So what does the United States have to do with it? I mean, you have these massive conflicts that have roiled the globe. Do we have a responsibility here?

KENNETH ROTH: Well, yes. If you look at why people are fleeing—let’s take the Syrians, who are the largest percentage. In an ordinary war, you can get some degree of protection by moving away from the front lines. But in Syria, Assad is dropping barrel bombs in the middle of civilian neighborhoods that happen to be controlled by the opposition. There is no safe place to move in Syria if you’re in opposition-held territory, which is why we have 4 million refugees from Syria today. So one very important thing to do is to go to the root causes of this, to try to put real pressure on Assad to stop barrel-bombing civilians, and to take comparable steps in the other major refugee-producing countries, like Somalia, Eritrea and Afghanistan. You know, let’s not forget why we have this crisis. It’s not that everybody woke up this morning and thought it would be nice to move to Europe. These people are being forced out because of severe conflict and persecution.
